Telnet Commands

To flash an image using Telnet

This method will only work with a .img image file.

Rename the image file to backup.img
FTP the image file to the /tmp folder on the dreambox
Telnet to your box and paste the following command:

Code:

cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot

To telnet, click START > RUN and type Telnet ip.address.of.dreambox
A command window will appear, enter username root and password dreambox.

To backup an image using Telnet

Telnet to the box and paste the following command:

Code:

cat /dev/mtd/3 > /tmp/backup.img

FTP to the box and navigate to the /tmp
Here you will find the backup.img file.

Now I get it.
Put .exe after telnet, eg telnet.exe

Guys, Help.

Just done the following:

Dowloaded the DW 2.0 image
Renamed to backup.img
Placed in tmp folder

Then followed the instructions below.

Telnet to your box and paste the following command:
Code:
cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot

My dreambox has now gone from terminally ill to deceased.

Powered up and nothing, no menu, graphic, not even a flicker. Just a very troubling black screen. I have now lost the connection to my laptop also.

Crap, my mate won't be pleased. Although it's his own fault for randomly pushing buttons after the NTL blackout.

you may have created more problems than solved m8, if its a bad flash you,ll need a null modem cable and dreamup software to rescue the box.

it will flash a new image to the box safely, i always use the null lead to send images to mine, it takes longer but is safer and you can rescue it if it goes tits up.

hopefully you already have a null modem cable at home, if so plug it in your pc and box and use dreamup software to send the image to the box.

for people who are not into telnet and fxp it is the easiest way to go.

start software select com port1 click connect, plug box in(power) then flash image, simple no going wrong but it takes a bit longer than the other ways.

Thanks for the guide Kaos. Saved me having to drag out the old PC with a serial port to flash my friends box with some bastardised version of Enigma on it.

I don't know the pass for my dreambox is there any way cracking it or reinstaling it without losing the settings or any way to backup or download the bouquets at least

Don't know what's best image so I picked the NabiloBlackHole_DM800_012 image. Q. Will ftp'ing it to /tmp dir and following the same telnet command apply this image to my DM800.
I did all this ages ago on my DM500, does the same process apply with DM 800?
what about cams etc, is there an idoits guide for DM800 on the forum somewhere, Sorry I am abit numpty due to lack of practise playing with Dreambox for more than a year or so....
